I think we're talking about two different things. I was addressing a section in the article about running databases backed by s3. It's less about s3 needing to act as a filesystem, and more about all of the rdbms features that come along with the various types of DB transactions. It's a solved problem with the libraries I mentioned. Not something I'd ever recommend to build on your own. Been there done that when those solutions were still nascent. Wasn't worth the effort vs just using an rdbms. The problem that emrfs is trying to solve doesn't cover the rdbms scenarios like row-level updates and deletes.
